Miscellaneous Production 23/87 - Animal Production In The Spinifex And Shrubland Regions Of Western Australia, D. Burnside

Animal production and livestock published reports

The role of the Rangeland Management Branch is to promote the sustained economic use of the rangeland resource. It provides research and extension services to the pastoral industry, provides advice on the condition of the range resource to Government and provides technical information on rangelands to other rangeland managers. A principal objective to be met in fulfilling that role is the development and promotion of economically efficient place systems that conserve the rangeland resource. At the inaugural Pastoral Soil Conservation Districts Conference in Meekatharra in May 1987, pastoralist delegates emphasized the importance of achieving that objective within the various soil …

Selecting For Carcass Merit, Norris J. Stenquist

Archived Agriculture Publications

Today's consumers are asking for leaner, less-fatty beef. Much of the leaner beef now produced results from trimming excess fat before the product is sent to the consumer. For the future, the hope is to trim excess fat genetically by producing leaner, more heavily muscled beef cattle.

Use Of Soybean Meal, Raw Soybeans, & Heat-Treated Soybeans As Protein Supplements With & Without Niacin For Dairy Cows In Early Lactation, Daniel Aguilar

Masters Theses & Specialist Projects

Twenty three cows with an average of 2.7 lactations were used to measure the effects of different protein sources (soybean meal, soybeans, and heat-treated soybean) and supplementation with niacin on milk production, milk components (protein, fat, somatic cell counts), 4% fat corrected milk, solid corrected milk, dry matter intake, body weight changes, and rumen volatile fatty acids (acetate, propionate, butyrate).

Diets affected performance of cows. The results indicate, in general, that feeding heat-treated soybean and soybean meal to lactating dairy cows in early lactation resulted in greater milk production, milk protein, dry matter intake and less loss of body weight …

The Awassi Fat Tail Sheep Project, R J. Lightfoot

Journal of the Department of Agriculture, Western Australia, Series 4

Australia's first Awassi fat tail lambs arrived at Kununurra in January 1987, completing the first major step in an ambitious project to establish a fat tail sheep breeding industry in this country.

Fat tail sheep bred in the Middle East attract much higher prices than merino wethers imported from Australia. The question to be resolved through our product development and market research is what premiums will Middle Eastern buyers pay for fat tail sheep bred in Australia and exported to the region.

The Department of Agriculture believes that there is potential for Sustralian producers to enter these new markets without …

The Antibody Production By Swine In Response To Sheep Red Blood Cells, Deborah Seymour

Masters Theses & Specialist Projects

Two experiments were conducted to study the antibody response of pigs challenged with the general antigen sheep red blood cells (SRBC).

In one experiment SRBC's were injected at one of four sties: intramuscularly into the neck, intramuscularly into the ham, subcutaneously into the fore flank or rear flank. These treatments were repeated four weeks later. The antibody responses to the four treatments were determined by microtiter and analyzed statistically. No significant (P> 0. 10) differences were found among responses to the four treatments during the fourth and eighth weeks after injections, but a significant (P<0.05) difference was found during the fifth week among all four groups. Coefficients of correlation showed highly significant (P<.0.01) relationships between SRBC antibody titer during the fourth week after injections and increase in weight of test animals from the beginning of the study until slaughter.

In a second experiment pigs …

The Relationship Between Linear Measurements & Subjective Placings In Elite Angus Cattle, Ted Dyer

Masters Theses & Specialist Projects

The cattle shown from 1981 to 1984 at the American Angus Breeders' Futurity were studied to determine the relationship between linear measurements and the judge's subjective placings. Linear measurements taken prior to the showing included wither height, hip height, and body length for both bulls and heifers. In addition body weight and scrotal circumference were recorded for bulls. A total of 624 cattle were studied-- 407 heifers and 217 bulls.

The cattle were divided into five groups by age and sex to analyze the annual difference in means and standard deviations for all recorded measurements. Among all five groups of …

Effect Of Rations On Some Selected Blood Constituents Of Dairy Heifers, Kamil Akanbi

Documentation Of Whole-Farm Model For The Eastern Wheatbelt Of Western Australia, Ross S. Kingwell, David J. Pannell, David. A. Morrison

Grain and other field crops published reports

The Eastern Wheatbelt Model (EwM) is a hypothetical farm model, intended to be representative of farms in the eastern wheatbelt region. It is a model of an 'average' farm in an 'average' season. Nevertheless it is possible to substitute the resource mix of a 'real' farm for the •average' and to substitute various types of season for the 'average'.

Assumptions of 'average' farm resources and •average' season are based on opinions by WADA researchers and advisers. For the EWM, researchers and advisers at Merredin prescribed average resources for an eastern wheatbelt farm receiving a 300 mm average rainfall including 210 …

The Secretive Silvereyes, I J. Rooke

Journal of the Department of Agriculture, Western Australia, Series 4

Durinf the past five years the agricultural Protection Board, in co-operation with scientists from CSIRO's Division of Wildlife Research and the University of Western Australia, had studied the biology and control of the silvereye in the South-West of Western Asustralia. The project was partially funded by a voluntary levy on vignerons in the Margaret River and Mt Barker areas.

The first part of the study investigated the bird's bioloogy - its food requirements, reproductive rate, how it interacted with other birds and its seasonal movements, It was hoped that this knowledge would help develop effective techniques for either controlling the …

Keeping Starlings Out Of W.A, John L. Long

Journal of the Department of Agriculture, Western Australia, Series 4

In Europe and North America huge flocks of starlings cause millions of dollars worth of damage to grain and fruit crops each year and large sums of money are spent trying to control them.

Starlings were introduced into australia in the late 1890s when more than 200 birds were released near Melbourne. They are now well established over much of eastern Australia, ranging from central Queensland, south to Tasmania and along the Great Australian Bight to the South Australian-Western Australian border, occasionally crossing it and sometimes moving as far west as the Esperance region on the south coast.

Bulletin Ma 20 - Sheep Yard Plans - Flocks Up To 500, D. Bicknell

Animal production and livestock published reports

Manjimup Regional Office

Owners of small flocks often use much more labour per sheep than do owners of large flocks. Most of the difference in labour use is the design of sheep sheds and sheep yards, and a smaller affect from the mob size and experience in handling sheep.

This booklet gives some detail on design and construction of yards and a number of yard plans to handle up to 500 or so sheep. Many of the plans are from an Australian Wool Corporation publicatiot1 "Wool Harvesting Notes".

The Problems And Prospects Of The Kimberley Pastoral Industry, R B. Hacker

Resource management technical reports

The pastoral industry in the Kimberley region began in the early 1880s withthe introduction of cattle overlanded from Queensland and New South Wales into the East Kimberley and with the almost simultaneous introduction, by sea, ofboth sheep and cattle into the Fitzroy Valley.Occupation of the more accessible areas was gradually achieved by theprogressive extension of these two arms of settlement which ultimately metaround the present location of Fitzroy Crossing. Extensive development of themore rugged areas of the North Kimberley came later with the construction ofreasonable access roads to the few isolated stations which had been initiallyestablished in this area.

Effect Of Herbicides On Performance Of Aerobic Dairy Lagoons, John D. Bottom, Joseph L. Taraba

Biosystems and Agricultural Engineering Faculty Publications

The herbicides glyphosate, bromacil, and dalapon were assessed for their affect on the oxygen uptake of microorganisms from an aerated dairy lagoon at 20 °C. The maximum recommended addition of herbicide active ingerdient to a lagoon is: glyphosate (isopropyl amino salt)—0.42 mg/L; bromacil—3.70 mg/L; and dalapon (85.8 percent Na salt and 14.2 percent Mg salt)—1.95 mg/L. In addition, microorganism isolates from the aerobic dairy lagoon were incubated under aerobic and anerobic conditions at room temperature to assess the effects of the herbicides. Under aerobic incubation, it was found that neither herbicide type nor herbicide concentration affected isolate growth. Under anaerobic …
